Love the air purifier. Very light weight, quiet. Seems effective at removing particulates. We have a large dog…it seems to help with removing doggy smells.

A fine replacement filter and easy to replace.

Still breathing, working well!

The item received was a returned item not packaged well and had slight damage. Otherwise, it works fine. Taking a star off for the packaging of the return item and with damage sold as new.

We have a blue air filter in our family room and had to re-order the filter for this component and it was nice to be able to do it through Amazon and not have to go through the Blueair website to do so and it arrived in perfect condition and was easy to install

Quality filter! Busts ANY KIND of odor!

Love mine! Use this in my hamsters room and definitely helps with dust and odor. Also we get a lot of forest fires where im from so this is a definite need for those bad days.

Fantastic! It eliminates the idor very quickly and I find my place much more cleaner the air that we are breathing

I was pleased to receive the filter I ordered, without delay. With the forest fire smoke heavy and problematic for our area, having this delivery in such a timely manner was most appreciated. All went smoothly, and is working without issue.

Nice design. Love the different settings. Lowest setting is barely audible but can increase if more circulation is needed. Good purchase.

Own box, great shape. A little pricey however it lasts awhile.
